YSH1 fuel pressure issue?

[boostjunkie]

I am tuning a 4.6 GT with a vortech non-intercooled kit.

No matter what we do the fuel pressure is at 57-61 lbs.

Fuel Rail Delta pressure Function is 40 psi across the board in the tune.

Any ideas?

Sounds like you might have a bad Fuel Rail Pressure sensor, have you tried changing this?
